Biel Crystal Manufactory and Lens Technology, Chinese sapphire makers, have expanded their production capacities, according to industry sources. The companies made the move due to the growing adoption of sapphire in wearable and smartphone applications. Biel Crystal and China’s Roshow Technology have apparently invested an additional CNY200 million ($32 million) in their JV (Biel Roshow Sapphire), which was established a year ago. Meanwhile, Lens Technology has established a subsidiary maker specifically for producing sapphire.
